Definitions

  • the membranes and membrane cartridges/modules described herein can be used alone or in combinations and can be disposed within an enclosed housing or submerged in a tank, either an open or closed tank.
  • the various membranes can be arranged in plate and frame or spiral wound configurations. Examples of various membrane configurations can be found in U.S. Patent No. 8,181,794, U.S. Patent Publication No. 2011/0036774, and PCT Publication No. WO2013/022945, the disclosures of which are hereby incorporated by reference herein in their entireties.
  • the various membranes described herein can be incorporated into a variety of osmotically driven membrane systems / processes. Examples of osmotically driven membrane processes are disclosed in U.S. Patent Nos. 6,391,205 and
  • the invention relates to a method of manufacturing a forward osmosis membrane.
  • the method includes the steps of providing a substantially planar substrate, casting a polymeric support layer onto the substantially planar substrate, and casting a polymeric barrier layer onto the polymeric support layer.
  • the barrier layer includes a plurality of layered double hydroxide nanoparticles substantially evenly dispersed within the barrier layer.
  • the step of casting the barrier layer includes the steps of introducing the layered double hydroxide nanoparticles into a solvent bath comprising a first monomer, introducing the substantially planar substrate and support layer to the solvent bath, subjecting the substantially planar substrate and support layer to means for dispersing the layered double hydroxide nanoparticles, introducing the substantially planar substrate and support layer to a second bath, wherein the second bath comprises a second monomer, and reacting the monomers to form the barrier layer and set the nanoparticles in place within the barrier layer.
  • the means for dispersing can include subjecting the solvent bath to an energy field, such as ultrasonic, electro-magnetic, or thermal, applied constantly or in a pulsed manner.
  • the means for dispersing can be applied to the solvent bath continuously as the membrane substrate and support layer are passed therethrough. Alternatively or additionally, the means for dispersing can be applied directly to the membrane substrate, for example, as it passes from the first bath to the second bath.
  • the fabric may be about 25 micrometers in thickness.
  • the forward osmosis membrane may be further characterized by polyamide interfacial polymerization on its surface.
  • a polyamide active layer may be applied so as to result in a membrane of any desired thickness.
  • the membrane may be approximately 25 micrometers thick.
  • the active layer of the forward osmosis membrane may be modified to enhance rejection of draw solutes.
  • the support film may be nonwoven and made of any material, but thinness, high porosity, low tortuosity, and
  • benzenetricarbonyltrichloride in Isopar RTM C or G at room temperature may be used.
  • the membrane may then be removed and the Isopar RTM allowed to evaporate from the membrane for a period of time, for example less than about 5 minutes. In some embodiments, the duration of the evaporation step may be about 2 minutes.
  • immersion may take the form of a dip coating process, such as one in which substantially only the surface of the membrane comes into contact with a solution. In other embodiments, the entire membrane may be submerged in the bath. In some embodiments, a combination of these techniques may be used, such as in a sequence of different immersion steps. In other embodiments, the heat treatment of the membrane may occur in any or several immersion steps intended for other purposes, such as during or after the active layer polymerization or deposition step.
  • FIG. 5 is a schematic plan view of a membrane module in accordance with one or more embodiments of the invention.
  • the module 300 includes two membrane sheets 301 attached to each side of the frame 303.
  • the membrane 301 is secured to the frame 303 by thermally bonding the membrane thereto by sonic welding.
  • the membrane 301 can be attached via solvent bonding, adhesive, or a mechanical fastening means (e.g., an additional frame and fasteners), so long as the entire perimeter 311 of the membrane sheet 301 is sealed to the frame 303.
  • the membrane sheets 301 will be oriented so that the same sides will be facing the interior of the frame 303. For example, if a draw solution is directed through the interior of the module 300, the permeate sides of the membranes 301 will be facing inward.
  • the frame 303" is made of two separate frames 303a, 303b, joined together via, for example, welding or mechanical means (e.g., fasteners or corresponding structure to enable a snap fit between the frame halves 303a, 303b, with or without a gasket).
  • the membranes 301" can be attached to the frame 303" via welding or other means and include sample ports 315" and / or protective layers 313".
  • the frame 303" is symmetrical.
  • the membrane 851 has a feed side that typically corresponds to the membrane barrier layer and a permeate side that typically corresponds to the membrane support layer.
  • the feed side is at a higher pressure than the draw side, which tends to push the membrane away from the feed and into contact with the draw screen.
  • the draw side which would then be the barrier layer side of the membrane, would be at the higher pressure
  • very thin membranes and in particular those that have a very thin support layer such as those made in accordance with the present assignee's commonly owned U.S. Patent No.
